Preamble

 

EST (electronic scoring targets) are installed at:

·         SISC, Cecil Park NSW – 10M, 25M and 50M – Sius Ascor

·         MISC, Melbourne VIC – 10M and 50M – Sius Ascor

 

What is in the various boxes

 

While the technical aspects of ‘how they work’ is transparent to the shooters, officials and spectators, the following Q&D explanation is provided for information:

·         The 10, 25 and 50M targets used in Australia consist of:

o   A box containing the target mechanism

§  There are four microphones located top left, top right, bottom left and bottom right located inside the target box

§  The main face of the target is a sheet of black rubber

§  A strip of black rubber (paper for 10M targets) runs down the face of the target – this advances after each shot is registered

§  The target face board (white corrugated plastic type of material) defines the black aiming mark.  This can be changed to give the appropriate sized aiming mark for the different events

§  The target box has a backing sheet of corrugated plastic type of material

§  For 25M, each box has a red light above, and a green light below the target

o   A monitor for each firing point.  This has a representation of the target showing:

§  The status of the target – ‘STOP’ is shown in lower right corner if the target is not ‘ready’ for shots

§  the top right corner shows a diagonal if the target is set to ‘sighters’

§  the location of the shot/s

o   A printer.  These are located on a table behind the firing points:

§  In normal use, each target’s printer will give the value of each shot and the subtotals

§  Each printer has a small LCD screen and number of control buttons

o   The printers in a range section are mounted on a table behind the firing bays.

§  For 25M each table’s printers are linked to a control box and all the 25M controllers boxes on a range can be daisy-chained for central control of the range

o   At the SISC range, each target also has an overhead display for the spectators.  This display shows the shot values, subtotals and progressive total.

·         The range Control Room has a computer linked to all targets on the range.  This computer can:

o   ‘Set’ the targets on that range for the event and the shooters in each individual bay

o   Collect the shot values

o   Collate the shot values for progressive and total scores at each firing point

o   Send the scores, subtotals and total score to spectator display/s

 

How they work

 

When a shot hits the face of the target:

·         The impact of the shot passing through the face of the target creates a ‘plopping’ noise

·         This impact is detected by the microphones

·         Unless the shot is perfectly central on the face of the target, this shot noise will be detected at different times for each microphone

·         The target’s system will compute:

o   the location of the shot (the x, y coordinates),

o   the time the shot hit the target, and

o   the value of the shot for the event/stage

·         the target’s system transmits this data to:

o   the shooter’s monitor/s (five monitors for Rapid Fire Pistol)

o   the overhead display (where installed), showing the shot values

o   the Control Room computer

 

Who is allowed to touch what

 

Control panels and printers

6.11.1.2.2 Shooters and Range Officials must not touch the printer control panels and/or printer strips before the end of the relay, or event, except when authorized by the Jury. Shooters should sign the printer strip (next to the score total) before leaving the range to identify their score.

 

The important bits in 6.11.1.2.2 are:

·         Shooters must not touch the printer control panels and/or printer strips… except when authorized by the Jury.  The only authorisation by the Jury would be for the shooter to sign the printer strip

·         Range Officials must not touch the printer control panels and/or printer strips… except when authorized by the Jury.  Unless there are designated technicians at a competition, the section Range Officer will normally:

o   Change the zoom at a shooter’s request (there are no controls for this at the 25M firing points)

o   Enter any missed shots

 

The Monitors

6.11.1.2.1 It is not permitted to obscure the shooter’s monitor-screen or any part of the screen. The whole screen must be visible to the Jury and range personnel.

 

‘…visible to the Jury and range personnel‘ does not mean that the Jury and range officials need to perform acrobatic tricks to be in a position to view the monitor screen:

·         The officials need to be able to check that the monitor is showing the correct information, and particularly that it is not showing ‘STOP’

·         The shooter may not have the screen covered

·         The shooter may not angle the screen such that it is not reasonably visible to the officials

·         The shooter may not dim the screen so that it is not reasonably visible to the officials

·         The shooter may angle the screen such that it is not readily visible the shooter, provided it is reasonably visible to the officials

 

The flying lead controller attached to the monitor

6.11.1.2 Electronic Scoring Targets It is essential that shooters familiarize themselves during training with the control buttons that alter the target presentation on the monitor screen (ZOOM facility) and that change from a Sighting target to a Match target (MATCH). In 10 m and 50 m events the change from sighters to match is under control of, and is the responsibility of, the shooter. If any shooter is in doubt, he must ask a Range Officer for assistance. In 25 m events the control and responsibility is by the range personnel.

 

The important bits in 6.11.1.2 are:

·         The shooter can change the zoom

·         For 10M and 50M the shooter can change from sighters to competition – the system is set up so they cannot change back from sighters to competition

·         There is a third button (‘MENU’) – the shooter must not operate this button

Setting up the targets

 

The white target faces:

·         are located by two precision-located holes (top and bottom) on to matching studs in the target box

·         access to the box to change the target face is by opening the face of the target box

o   for 25M targets, disconnect the lead to the red light FIRST

o   for 25m and 50M targets the face of the box is hinged at the bottom edge and opens about 20cm

o   for 10M targets the face of the box is hinged on the right edge

 

Before closing the target box:

·         ensure that the strip is located centrally down the target

·         ensure that the target face is properly located on the studs (top and bottom)

·         for 10M ensure the switch is correct for rifle / pistol

·         for 25M ensure that the switch is set to the appropriate rimfire/centrefire setting

 

After closing the target box:

·         Visually re-check that the target face is central

·         Visually re-check that the strip is located centrally down the target

·         Check that the strip advances when the target box is closed

·         For 25M targets, reconnect the lead to the red light

 

For 25M targets, after the range has been set up, operate the targets and check that all red and green lights are working – if no shots are fired, this will not upset the system.

 

Be aware that for 10M, closing the box will usually send a ‘shot received’ signal to the Control Room computer for that target – all 10M targets must be checked, etc. before the Control Room computer sends the event data to the targetry

 

Setting up the controls

 

If the range is being controlled by the Control Room personnel:

·         Data will be sent to the ‘main’ printer table controller

o   This data will also be sent to any set of targets connected to the ‘main’ printer table controller

·         Data will be sent to the targetry, including:

o   the shooter’s name – this will be displayed on the shooter’s monitor and (after the first shot) on the printer strip

o   the event/stage

o   whether sighters, competition or Finals

·         when this data is transmitted to the range:

o   any previous scores on the monitors is cleared

o   any previous data on spectator displays is cleared

o   the printer strips will advance and show the shooter’s name after the first shot

·         the time sequence will be set by the CRO at the on-range master controller – this must be verified by a second range official

·         the Range Officers must check that:

o   the shooter’s name is displayed on the monitor

o   the monitors  for bays in use are not displaying ‘STOP’

o   both green lights are on for the shooter’s printer

 

If the range is being controlled independently:

·         the shooter’s name will need to be hand printed in the printer strip

·         the shooter’s name will not appear on the monitor

·         each target will need to be set from the target’s printer panel for

o   sighters/competition/Finals

o   the event/stage

 

Setting up for Rapid Fire Pistol

 

Setting up for RFP is a bit different from the other events:

·         Each shooter gets five monitors

·         Only the central printer (of five) records and prints shot values/subtotals/total – the other four printer controls can be set to only one green light (though this is not essential, they will just be passive in any case – but it is a shame to waste printer paper)

·         Only the central printer controls the target settings

 

Changing the ‘zoom’

 

The flying lead controller has been removed from the 25M targets at SISC – changing the zoom of the monitor is done by a range official from the printer controls

 

For 10M and 50M, the shooter can change the zoom from the flying lead controller attached to the monitor.  While this action is normally performed by the shooter, it is permissible for the shooter to ask a range official to perform the zoom change from the printer.

 

‘Clear Log’

 

Any ‘clear log’ action will remove the data of previous shots from the range system – if the Control Room computer has been in operation (and the data properly saved to the hard disc) the shot data can be recovered.

 

6.7.11.3 No CLEAR LOG must be made before the Classification Jury has given permission. AND should only be done from the Control Room

 

Control of targets from the Control Room

 

The Computer control will only affect those targets selected at the computer, and those targets connected to the control Room computer

 

‘Start’ signal from the Control Room computer

 

If the range is connected to the Control Room computer, when ‘start’ is activated at the computer:

·         All data displayed on the monitor and spectator displays is cleared

·         The shooter’s name appears on the monitor

·         The targets are set to the event/stage (usually sighters)

·         Once the target registers the first shot the printer paper advances with the shooters name, event, and stage

 

This ‘start’ from the Control Room computer does not start the event/stage – it is only setting the range for the stage/event.  The Chief Range Officer still controls the event by giving the range commands (and initiating the sequence for 25M)

 

‘Stop’ signal from the Control Room computer

 

This action is not the same as ‘Clear Log’

 

If the range is connected to the Control Room computer, when ‘stop’ is activated at the computer:

·         No further shots will be recorded for the stage/event by the targetry (it should not happen, but…)

·         The printer paper will advance and the total for the match/stage will be printed – the paper advances sufficiently for the shooter to sign the printer strip 6.11.1.2.2 …Shooters should sign the printer strip (next to the score total) before leaving the range to identify their score.

 

It is essential that the CRO, Range Officers and Jury members have resolved any scoring problems that might require additional shots BEFORE the signal to ‘stop’ the targetry is sent to the Control Room!

Changing from sighters to competition at 25M

 

If the range is connected to the Control Room computer, the technician will send the appropriate signal to the targetry.  When this happens:

·         All data displayed on the monitor and spectator displays is cleared

·         The shooter’s name reappears on the monitor

·         The printer paper advances with the shooters name, event, and stage for competition shots

·         The targets are set to the event/stage

 

It is essential that:

·         the CRO:

o   gives the shooters sufficient time to view their shots (about 30 seconds)

o   clearly signals to the Control Room technician that the targetry can be changed to competition, and

o   receives a signal that the signal to change has been received

·         after the change to competition shots the section Range Officers check

o   All targets in use on the section are operating

o   No monitor displays ‘STOP’

o   All monitors for bays in use display the shooters name

o   The sighters diagonal has cleared from the monitor

 

If the range is not connected to the Control Room computer, the technicians (if not available, then the Range Officers) will need to change over the targets manually. (select match, stage)

 

It is essential that the Range Officers:

·         give the shooters sufficient time to view their shots (about 30 seconds)

·         after the change to competition shots the section Range Officers check

o   All targets in use on the section are operating

o   No monitor displays ‘STOP’

o   The sighters diagonal has cleared from the monitor

 

Entering missed shots

 

‘Zeros’ on the target

 

All shots on the face of the target, but outside the scoring area, will register on the system as ‘0’.  No action is required by the range officials or technicians

 

Frame hits

 

All shots on the frame of the target box will register on the system as ‘0, frame hit’.  No action is required by the range officials or technicians

 

Late shots

 

All late shots will register on the system (value, x,y coordinates and system time) but:

·         For 25M, only a zero ‘0’ will show on the monitor, printer and spectator display

·         For 10M and 50M:

o   ‘STOP’ will appear on the monitor after the regular number of shots

o   The  shot/s will not be displayed on the spectator display – the shot/s will be displayed on the monitor

·         The value, x,y coordinates and system time of the late shot/s can be recovered from the Control Room computer (if connected to the targetry)  and the printer (provided the log has not been cleared)

 

10M and 50M

 

If a shooter fires a competition or Finals shot that misses the target, this must be registered on the printer strip and a ‘Range Incident Report’.  It is important that the sequence of the shot/s be recorded

 

For 10M this process includes any discharge of propellant after the shooter has switched to competition shots

 

25M Standard Pistol

 

If the shooter has any shots that miss the target, or shots unfired in the time series (including malfunctions), the series is totalled from the printer controls (total, seq) before the next series.  This includes any shot after LOAD but before the series starts, and any shot unfired when the shooter runs out of time.  The required number of zeros will appear on the printer strip and the spectator display.

 

25M Precision and Rapid Fire Stage

 

If the shooter has any shots that miss the target, the series is totalled from the printer controls (total, seq) before the next series.  This includes any shot after LOAD but before the series starts, and any shot unfired when the shooter runs out of time.  The required number of zeros will appear on the printer strip and the spectator display.

 

If the shooter has shots to complete after an allowable malfunction, do nothing to the printer controls – the completion shots will automatically ‘come up’ on the printer and display.

 

If the shooter has unfired shots from a non-allowable malfunction, the series is totalled from the printer controls (total, seq) before the next series.  The required number of zeros will appear on the printer strip and the spectator display.

 

25M Rapid Fire Pistol

 

For RFP, no action is required – at the completion of each series any targets without a hit will display a ‘zero’ on the printer strip and the display.

 

Changing back from competition to sighters – 10M and 50M

 

It is possible!

While the shooter cannot change back to sighters from the firing point controls, it can be done from the printer – simply change the target setting from competition to sighters.

 

There are only two circumstances when this procedure is necessary:

·         6.12.2.2 Extra time and additional sighting shots must only be granted if the interruption is not due to a fault of the shooter.

·         6.11.4.2.2 if the shooter is aware of the situation, he must raise his nonshooting hand to indicate to a Range Officer that he has a problem. A Range Officer must then supervise the unloading of the gun and no penalty will be incurred. No extra time will be allowed, but the shooter may continue in the normal way; - the obvious way to unload an Air Pistol (or rifle) is to discharge it in a safe direction; the target is a safe direction!  Simply set the targets to ‘sighters’, have the shooter fire the shot and reset the target to competition.

 

Changing back from competition to sighters – 25M

 

Unlikely, but…

…change the target setting at the printer controls from competition to sighters.

 

Malfunctions

 

It is essential that the CRO is aware of any malfunction/s

 

At the completion of the series (and not before):

·         Inspect the pistol as per ISSF rules

·         Announce allowable or non-allowable
